Constructor Detail

MessageBlock

public MessageBlock(PlainText... messages)

MessageBlock

public MessageBlock(java.util.List<? extends PlainText> messages)

MessageBlock

public MessageBlock(org.cryptimeleon.math.structures.cartesian.Vector<? extends PlainText> messages)

MessageBlock

public MessageBlock(org.cryptimeleon.math.serialization.Representation repr,
                    java.util.function.Function<org.cryptimeleon.math.serialization.Representation,? extends PlainText> messageRestorer)

Reconstructs the message block from its representation.

Caller needs to supply a function messageRestorer that is used to restore each message in this block (e.g., repr -> new RingElementPlainText(myRing.getElement(repr)).

Parameters:

repr - the representation to restore the message block from

messageRestorer - a function that can restore the message representations contained in the message block representation

updateAccumulator

public org.cryptimeleon.math.hash.ByteAccumulator updateAccumulator(org.cryptimeleon.math.hash.ByteAccumulator accumulator)

Specified by:
